Wow, you're right trumpet. We really are in very similar situations!!
I think you are doing a better job of not pushing R talk that I am. My W doesn't resist this kind of talk, but the result it seems to produce it that it pressures her at a time when she's just not in a place to make a favorable decision. So for different reasons, I'm in the same boat of having no choice but to back off.
I'm curious with the addiction whether you feel that masturbation without porn would be a morally acceptable way to "take care of yourself" when your W cannot. I know people have different views on this. I came to a decision for myself that it's about keeping my sexuality "sacred" by not leaking it with porn which can encourage a disassociation between the physical and emotional/spiritual aspects of sex. The goal here is to maintain a "sacredness" to one's sexuality which to me means that the physical, emotional, and spiritual aspects should all be balance with each other. This is the important thing for real sex with a real woman, as I see it. So, perhaps masturbation using only imagination can be a healthy, personal thing which can be done with self love in a way that has the emotional/spiritual aspects to it? Not sure if that really helps, but I thought I'd offer my perspective.
